anaconda vs /etc/mtab -- fixed recently?

[Jeffrey Law <law redhat com>]

In late 2006 I stumbled upon a bug in which anaconda would throw an
exception if a %post script changed /etc/mtab to be a link to 
/proc/mounts.

I had assumed this was due to anaconda's attempts to update /etc/mtab
as it unmounted filesystems before it exited.  I even went as far
as to strace anaconda to verify it indeed was mucking around with
/etc/mtab after the %post script ran.


However, I went to reproduce (and then fix) this problem today, but
couldn't reproduce it.

Does anyone know for sure if this was fixed?  Or should I dig deeper
to see if there's another element necessary to trigger the failure?
(the original kickstart that triggered this failure had a lot of other
stuff in its %post that perhaps could play a role in triggering the
failure).
